Cheney has been outspoken on the issue ever since Rep. Ilhan Omar, D-Minn., suggested politicians who back Israel have allegiance to a foreign country. A House resolution later condemned bigotry. Rep. Alexandria Ocasio-Cortez questioned why there was no outrage over 23 Republicans who voted against the resolution.

Cheney shot back on Twitter: "Here's the outrage: your party put a sham resolution on the floor designed to protect the anti-Semitic hate and bigotry of @IlhanMN."
